Overview

Group A streptococcus and staphylococcus[1] are the most common causative agents of cellulitis. These bacteria are part of the normal flora living on the skin.

Causes

  • The causative pathogen of cellulitis varies with the anatomical location and the patient’s medical and exposure history.
Predisposing factor, anatomical location, and likely etiology of cellulitis[2]
Predisposing Factor Anatomical Location Likely Etiology
Periorbital (preseptal) cellulitis Eyelid and periocular tissues Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes
Buccal cellulitis in children without Hib vaccine Cheek Haemophilus influenzae
Cellulitis complicated by body piercing Ear, nose, umbilicus S. aureus, S. pyogenes
Perianal cellulitis Perineum S. pyogenes
Subcutaneous injection of illicit drugs (“skin popping”) Extremities, neck S. aureus, Streptococcus (group A, C, F, G)
Breast surgert with axillary lymph node dissection Ipsilateral arm Non–group A hemolytic Streptococcus
Harvest of saphenous vein Ipsilateral leg Group A or non–group A hemolytic Streptococcus
Crepitant or gangrenous cellulitis Extremities, Trunk Clostridium or non–spore-forming anaerobes; alone or with E. coli, Klebsiella, or Aeromonas
Diabetic foot ulcer Dorsum of foot or toes S. aureus, Streptococcus, Enterobacteriaceae, P. aeruginosa, Acinetobacter, or anaerobes
Exposure to salt water at breeches of skin Extremities Vibrio vulnificus
Exposure to fresh water at breeches of skin Extremities Aeromonas hydrophila
Medicinal leech therapy Extremities Aeromonas hydrophila
Working as a butcher, fish or clam handler, veterinarian Fingers Erysipelothrix rhusiopathiae
